When running Pipelines jobs, you might run into the following YAML parsing error:

    Failed to parse the acquia-pipelines.yml file.
    The build definition file contains a syntax error.                                                                                              

This means your `acquia-pipelines.yml` file is malformed. Navigate to [yamllint.com](http://www.yamllint.com) to check your YAML syntax and fix any issues found.

Note

After you fix any detected issues with any pipeline jobs, run the `start` command again to restart the build.
